The AD5259 library allows Arduino users to interface with the Analog Devices AD5259 digital potentiometer via I²C. This library provides functions to read and write values to the RDAC register, store settings in EEPROM, and reset stored values.

• Read and write RDAC values (0-255)
• Store and retrieve values from EEPROM
• Check device connection over I²C
• Reset EEPROM to a default value
• Built-in timeout handling for I²C communication

1. Download or clone this repository.
2. Copy the AD5259 folder into your Arduino libraries directory.
3. Restart the Arduino IDE.

#include <Wire.h>
#include "AD5259.h"

AD5259 potentiometer(0x18); // Default I2C address

void setup() {
    Serial.begin(115200);
    Wire.begin();
    
    if (potentiometer.begin()) {
        Serial.println("AD5259 detected!");
    } else {
        Serial.println("AD5259 not found!");
    }
}

potentiometer.write(128); // Set RDAC to midpoint
uint8_t value = potentiometer.read();
Serial.print("RDAC Value: ");
Serial.println(value);

potentiometer.writeEEPROM(200); // Save value to EEPROM
uint8_t storedValue = potentiometer.readEEPROM();
Serial.print("Stored EEPROM Value: ");
Serial.println(storedValue);

potentiometer.resetEEPROM(128); // Reset to 128
